Summaries for Pyropoikilocytosis

About this section


OMIM:45 Hereditary pyropoikilocytosis was originally described by Zarkowsky et al. (1975) as a distinct hemolytic anemia... (266140) more...

MalaCards based summary: Pyropoikilocytosis, also known as hereditary pyropoikilocytosis, is related to hereditary elliptocytosis and hereditary spherocytosis, and has symptoms including autosomal recessive inheritance, hemolytic anemia and elliptocytosis. An important gene associated with Pyropoikilocytosis is SPTA1 (spectrin, alpha, erythrocytic 1 (elliptocytosis 2)), and among its related pathways are L1CAM interactions and NCAM signaling for neurite out-growth. Affiliated tissues include testes, and related mouse phenotypes are liver/biliary system and renal/urinary system.

Wikipedia:63 Hereditary pyropoikilocytosis (HPP) is an autosomal recessive form of hemolytic anemia characterized by... more...
